Application filed February 25, 1903, Serial No. 144,950. Renewed June 14, 1904;. Serial No. 212,506.

To all who-m. 2'25 may concern Be it known that we, CHARLES E. ISAKSON and JOHN D. E. ISAKSON, citizens of the United States, and residents of Brooklyn, county of Kings, and State of New York, have invented certain new and; useful Improvements in Engine-Room Telegraph-Recorders, of which the following is a specification.

This invention relates to telegraphs on board ship, used for giving signals from the bridge or other part of the vessel to the engineer in charge of the engines.

The object of the invention is to provide a new and improved recorder, arranged to produce a permanent record of the signals transmitted by the telegraph to the engine room. to record the forward or backward running of the engine, and to record the time at which the signals were sent or the direction of the engine changed.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and pointed out in the claims;

A practical embodiment of the invent-ion is represented in the accompanying drawings forming a part of this specification, in which similar characters'of reference indicate" corresponding parts in all the views.

Figure 1 is a face view of the improve ment as applied; Fig. 2 is a sectional plan view of the engine room dial. and part of the connection with the recorder; Fig. 3 is a transverse section of the same, on the line 33 of Fig. 2; Fig. 4 is a plan view of the improvement, parts being in section; Fig. 5 is a face view of the same; Fig. 6 is a transverse section of the same; F 7 is a sectional front elevation of the same, parts being broken out; and Fig. 8 is an enlarged transverse section of the recording pencil and its holder.

Theengine room telegraph on board a marine vessel usually consists of similar dials A, and B. of which one is located 011 the bridge and the other in the engine room, and on the dials indicate pointers C and D,

.. connected with each other by a suitable long-distance controlling means, such asthe mechanism E, to cause the pointers tomove in unison and to indicate alike on thegraduations. of the dials A and B. Thus,'when the pointer G is moved by the officer in charge of the vessel, say to indicate slow ahead on the dial A, then the pointer D moves to a corresponding position on the graduations of the dial B, for the engineer correspondingly shaped head F of a pivot pin- F, extending through a cam slot G formed in a cam G. held in a fixed position on the stationary diaLB. The outer end of the pivot pin F is pivotally connected by a link H with a bell crank lever H, fulcrumed on the stand or framework I of a recorder Llocated preferably in the immediate neighborhood of the dial B in the engine room of the vessel. The bell crank lever H is connected'by a link H with the rear arm J of a pencil carrier, supporting in its front arm J 2 a pencil J, adapted to trace a line on a web K, unwinding from a drum L and winding up on a drum L, as plainly shown in the drawings, the drum L and L being journaled in suitable beari gs on the stand I, and the drum L receiving a continuous rotary .motion from a clock N, by a suitable intermediate mechanism. as shown. clock N is also preferably mounted on the stand I. The pencil J is held in contact with the web K by a spring J arranged in ver H and link H imparts an upward or downward movement to the pencil holder and its pencil J, for the latter to correspondingly trace aline on the web K in a vertical The direction, as plainly indicated in Figs. 1

and 5. The web K is provided with graduatio'ns K, indicating time, and as the web is.

caused to travel past the pencil J by the clock N, it is evident that the graduations' K" indicate the exact time at which the pencil J is moved up or down on the web K. Thus a permanent record is made, indicat ing the signals transmitted by the telegraph dicating plate 0 is provided, extending in frontof the web K and securedto the framework I, and on the face of said indicating plate 0' are arranged gr'aduations corresponding to the graduations on the dials A and B (see Fig; 5). The upper end of the plate 0 is provided with an index finger 0', indicating on the graduations K and in vertical alinement with the pencil J v The gearing for turning the drum L from the clock N' may be' of any approved construction, and is preferably provided with a pinion L adapted to be thrown out of mesh with a-pinion L on a' shaft L, to.

allow of turning the drum L by hand whenever a new web K is placed in position on the drums L, L. The pinion L is pressed on by a spring L and is mounted to slide on its shaft L", but is normally held in mesh; with the pinion L by the spring L.

On the web K, preferably near the lower end thereof, a second line is traced by a pencil P, to indicate the reversing of the engine. The pencil P is mounted in a lever P, fulcrumed on the stand I and connected with 'the piston-rod Q of a piston Q, mounted to reciprocate in a vertically disposed cylinder Q, held on the stand I. The bottom of this cylinder Q is connected by a pipe R with an air-pump S, driven from the main shaft T or other part of the engine, so that when the engine runs in a forward direction, the air pressure, sent by-thepum S by way of the pipe R into the cylinder 2 acts on the piston Q therein, to hold the lever P and pen cil P in the positions shown in Figs. 1 and 5.

' Now when the engine is reversed, the pump- S is reversed, and consequently the air pressure 1s drawn out of the cylinder Q and the piston Q therein is forced downward by at mospheric pressure, to impart a swinging motlon to the lever P and thereby move the pencil P upward, to make a corresponding mark on the web K. Now the pencil P stands in vertical alinement with the pencil J and the pointer 0, so that the line traced by theysaid pencil correctly indicates the time at which" the engine is reversed, and when the engine is again caused to run forward, then the pump forces the air back into the cylinder Q, to change the position of the piston therein and thereby move the pencil back to its former position, thus agaln indicating on the web K the time at which the running direction of the enginetion between the marker and the pivot-carried by the pointer; as set forth.

2. In an engine room telegraph recorder, the combinationof a dial, a pointer therefor,

a slotted cam on the dial, a pivot slidably connected with the pointer and working 1n ,the slot of the cam, means for holding a traveling Web, a slidablemarker for indicating on the web, a bell crank lever having one member connected with the marker, and a link connecting the other member of thebell crank lever [With the pivot carried bythe pointer, as set'forth;
